MOTOR.

SPECIFICATION forming part of Letters Patent No. 643,078, dated February6, 1900.

Application filed April 17, 1899.

To all whom it may concern:

Be it known that I, FREDERICK F. ANDER- SON, of New York, county of NewYork, and State of New York, have invented certain new and usefulImprovements in Motors, of which the following is a specification.

My invention relates to motors for operating fans, sewing-machines, andother objects which can be operated with light power; and my object isto produce a device of this character, to be sold at a figure within the'means of practically every household, which will serve as a practicalsubstitute for electric, steam, or air power, forces which can beutilized by a relatively small number of people.

A further object is to produce a spring-motor, which will run for a longperiod of time without the necessity of being rewound, of simple,strong, durable, and inexpensive construction.

The invention consists, essentially, of a plurality of wheels, springssecured thereto, and dogs for engagement with said wheels to preventtheir rotation, a shaft geared to the shaft of said wheels and adaptedto impart motion to a fan or other object, and automatic means forsuccessively tripping said dogs and thereby utilizing successively thepower of said springs to drive the fan or other object, said automaticrelease tripping one dog just before the power of the preceding springis exhausted.

The invention further consists in certain novel and peculiar features ofconstruction and combinations of parts, as will be hereinafter describedand claimed, and in order that it may be fully understood reference isto be had to the accompanying drawings, in which- Figure 1 represents ahorizontal section of the casing containing a spring-motor embodying myinvention. Fig. 2 is a vertical section taken on the line II II ofFig. 1. Fig. 3 is avertical section taken on the line III III of Fig. 4.Fig. 4 is a vertical section taken on the line IV IV of Fig. 1. Fig. 5is an enlarged view, partly broken away, of the automatic release, thefeed-screw and guide-rod on which said release is mounted and travelsbeing shown in section. Fig. 6 is a View of the same, show- 50 ing theface of its trip-arm.

In said drawings, 1 designates'the base upon Serial No- 71S,423. (Nomodel.)

which the casing 2, preferably of rectangular form, is mounted, saidcasing being open at one end and provided with a hinged door 3 ducedthrough the opening 5) and the other end diametrically'reduced to formthe shoulder 11, which bears against the standard 8 and prevents theshaft creeping in that direction.

13,14, 15, and 16 designate small ratchetwheels, which are keyed orotherwise rigidly secured upon the shaft 9, and 18 asmall gearpinion,which is also keyed upon said shaft at a point between ratchet-wheel 16and the standard 8.

i '19, 20, 21, and 22 designate ratchet-wheels journaled upon the shaftbetween the standards 7 and the ratchet-wheels 13, 14, 15, and 16,respectively, and each of said Wheels is provided with a circular flange23 and a pin 24, and inclosed by said flanges and secured at their innerends to the pins 24 are the bar rel-springs 25, the outer ends of saidsprings being secured to the pins 26, projectingfrom standards 7. Toprevent said springs revolving said wheels at inopportune time-s, eachwheel carries a pivoted dog 27 for engagement with its respective orcompanion ratchetwheel 13, 14, 15, or 16, and said dogs are held inengagement with said ratchets by the springs 28, also carried by saidwheels, (see Fig. 3,) it being noticed in this connection that the teethof the ratchet-wheels keyed to the shaft are disposed oppositely to theteeth of the ratchet-wheels journaled upon said shaft, the latter, whenoperated by the power of the springs, turning in the direction indicatedby the arrows at, Figs. 2 and 3, and under the power of the shaftthrough the medium of a key or wrench in the direction opposite to thatindicated by said arrows, this movement of the shaft being imparted tosaid wheels successively by reason of the engagement of the keyedratchets with the dogs carried by the journaled ratchet-wheels, as willbe readily understood by reference to Fig. 3.

Keyed upon the shaft 9 adjacent to the standard 8 is a large cog-wheel29, which meshes continuously with a small cog-wheel 30, keyed upon ashort shaft 31, journaled in a U-shaped standard 32, and said shaft alsocarries rigidly a large cog-wheel 33, meshing continuously with a smallcog-wheel 34, keyed upon a short shaft 35, which shaft is journaled in aU-shaped standard 36 and carries a large cog-Wheel 37, meshingcontinuously with a small cog-wheel 3S, journaled upon a short shaft 39,projecting through the casing and journaled in a U-shaped standard 40within the latter, this shaft in practice being adapted to impart motionto afan 41, mounted thereon or otherwise geared thereto or to asewinganachine, churn, or otherdevice requiring only acomparativelylight power to operate it.

By the gearing interposed between the drive-shaft 9 and the shaft 39 itis obvious that the exceedingly slow movement of the former, ashereinafter referred to, is transformed into the exceedingly rapidrotation of the latter.

In order to utilize the power of the springs 25 singly or successively,I employ a mechanism constructed as follows: 42 designates a feed-screwextending parallel with shaft 9 and journaled at its opposite ends inthe bearing-standards 43 44, secured to the casing, and 45 a largecog-wheel keyed thereon and meshing continuously with the gear-pinion 18of shaft 9,s0 that the rotation of said shaft shall impart relativelyslow rotation to said feedscrew. Arranged forward of the cog-wheel 45 isa bearing-standard 46, and secured at its opposite ends in said standard46 and standard 44 and parallel with and adjacent to the feed-screw is aguide-rod 47, and vertically below said guide-rod and also connectingsaid standards is a pivot-rod 48, upon which are pivoted at properintervals the dogs 49, 50, 51, and 52 for engagement, respectively, withthe journaled ratchet-wheels 19, 20, 21, and 22, said dogs being heldyieldingly in the path of said wheels by weighting their opposite ends,as at 53, though it is obvious'that the mechanical equivalent of thisconstruction will perform the function of holding the dogs yieldingly inengagement with the wheels. In order to trip said dogs successively, Iprovide a traveling release consisting of the lower member 54 and theupper member 55, pivoted together at one end, as shown at 56, andadjacent to said pivot 0r hinge point provided with registering notcheswhich conjointly form a threaded opening 57, engaging the feed-screw 42,said'members being provided also with registering notches which conjointly form the circular opening 58, through which the guide-rod 47extends, this guide-rod serving to prevent the release oscillating uponthe screw, and thereby holding the depending trip-arm 59 perfectlyrigid, said trip-arm being provided with a bevel or cam face 60 at itslower end, which is adapted under the movement of the release upon thefeed-screw to successively engage the upper sides of the dogs 49, 50,51, and 52 and force them out of engagement with the wheels 19, 20, 21,and 22, the release traversing rearward toward the wheel 45 under therotation of the screw in the threaded opening 57, as will be readilyunderstood. To make this traveling movement from front to rear of therelease absolutely positive and reliable, however, it is necessary toclamp the members of the re lease together, and this I accomplish in asimple and inexpensive manner by providing the members with registeringnotches 61 62 and pivoting in notch 61 the bolt 63, carrying at itsouter end a clamping-n ut 64, so that when the bolt is swung upward intothe registering notch 62 a turn or two of the nut will cause it to bearupon the upper side of member 55, and thereby hold said members reliablyto gether.

Supposing the springs to be unwound and the release consequentlyoccupying a position adjacent to the cog-wheel 45, it is necessarybefore rewinding the springs to unscrew the nut 64 and throw it from theposition shown in Fig. 2 to the position shown in Fig. 5. When this isdone, the operator can pivotally open the release a sufficient distanceto permit it to be slid freely back to its original position at thefront end of the screw, as shown in Fig. 1, and then the members areclamped together again, as before. now introduced through the opening 5and engaged with the squared end of the powershaft and the latter turnedin the direction opposite to that indicated by the arrows, which actioncollectively re winds and restores the power of the springs 25, thekeyed ratchetwheels 16 in this operation imparting movement, through themedium of the spring-actuated dogs 27, to the journaled ratchet-Wheelssecured to the inner ends of the springs, While the gravity-dogs 49, 50,51, and 52 prevent the springs from unwinding.

If it is desired that the motor shall begin to operate as soon as thewinding operation ceases, the release should be positioned so that thefirst dog 49 shall be depressed or tripped by said release, and therebyoffer no opposition to the rotation of the wheel 19 under the action ofits spring at the instant the wind ing operation is completed; but if itbe desired to so construct the machine that it may remain inoperativeafter being wound up the release should be adjusted to a point forwardof said dog 49. In this latter case, however,

when it is desired to start the motor it will be necessary to trip thedog 49 by hand and hold it in such position until the screw has beenrotated sufficiently to dispose the trip-arm of the release in the pathof the dog, said release of course moving rearwardlyat an exceedinglyICO A key or lever is low rate of speed,the rate of speed of course being proportionate to the length of time which the spring 25 willoperate, so that just before the power of the first spring is exhaustedsaid release will have moved rearward upon the feed-screw a sufficientdistance to trip the second dog 50, holding the second spring 25 incheck, to the end that said second spring shall take the load off thefirst spring and keep the motor in operation until the release reachesand trips the third dog 51 and releases the third spring, theseoperations being repeated until all of the dogs have been tripped andthe last spring is dead or exhausted.

The drawings and description of course refer only to a limited number ofsprings and companion parts; but it is obvious that any desired numbermay be employed and that an increase in the number of course means anincrease in the length of time which the motor will run without thenecessity of rewinding it.

From the above description it will be apparent that I have produced aspring-motor which embodies the features of advantage enumerated asdesirable in the statement of invention, and it will be understood thatwhile I have shown and described the preferred embodiment of myinvention I reserve the right to make such changes as properly fallwithin the spirit and scope of the invention.
